LP-EM-CC2340R53: Bluetooth forum



Tool/software:

Hi Experts,

Greetings!

We have designed our BLE module using the CC2340R53N0RKPR (64KB variant) chipset and recently received the samples. In our design, we have selected the following default bootloader UART pins:

  • TXD: DIO20_A11

  • RXD: DIO22_A9

Could you please confirm if the selected I/Os are correct? Client wants serial bootloader functionality for firmware update process - for blank IC's & for Already flashed IC's (*With valid CCFG).

Looking forward to your confirmation.

Best regards,
Harinder Singh
